AlM:To observe the changes of binocular vision in V-pattern exotropia children before and after surgical correction, and the effect of training in reconstructing the binocular vision after surgical corrections.METHODS: Sixty V-pattern exotropia children were enrolled in this study and were divided into three groups according to their age:group A (4~6 years old), group B (7~9 years old), and group C (10~12 years old), 20 cases for each group. Patients received routine refraction and ophthalmic examinations. Distance and near deviation were measured by prism-covering method and synoptophore. The simultaneous perception and fusion were examined with a synoptophore, and the stereacuity was measured with stereograms ( Titmus) . The children who didn’t reconstruct binocular vision function 1wk after surgery received binocular vision training. The data were recorded before and 1 , 2, 4, and 8wk after surgery. RESULTS: Binocular vision significantly improved among the children after surgery in group A and B ( P<0. 05 ) . Significantly divergence showed between group C and the other groups 1wk after surgery ( P < 0. 05 ). Binocular vision of the three groups all significantly improved 8wk after surgery, with no significant differences (P>0. 05). CONCLUSlON: V - pattern exotropia children can benefit from early surgical correction and training after surgery in reconstruct binocular vision.

AIM To investigate the effect of fenofibrate and simvastatin on the serum free fatty acids of alcoholic fatty liver in rats. METHODS The rat model of alcoholic fatty liver was reproduced by chronic ethanol ingestion plus olive oil diet. The model rats were divided into three groups as follows: finofibrate treatment group(finofibrate 80 mg?kg -1 po, once a day),simvastatin treatment group (simvastatin 4 mg?kg -1 po, once a day)and control group without either above-mentioned treatment. Experimental rats were treated for four weeks and then sacrificed for blood sampling. Serum free fatty acids were analyzed by gas chromatography. RESULTS Fenofibrate significantly ameliorated the decrease in polyunsaturated fatty acids induced by ethanol [oleic acid:(38.212?7.788) ?g?L -1 vs (31.620?6.142) ?g?L -1,linoleic acid:(37.269?8.065) ?g?L -1 vs (30.254?9.063) ?g?L -1,arachidonic acid:(11.646?2.601) ?g?L -1 vs (9.012?1.236) ?g?L -1] accompanied by the improvement of the fat infiltration of the liver, but demonstrated no effect on the increase in serum saturated fatty acids by ethanol. In the contrast, simvastatin can aggravate the decrease in polyunsatrurated fatty acids and significantly increase the levels of satrurated fatty acids in serum induced by ethanol along with the pathological aggravation of alcoholic fatty liver. CONCLUSION The results of present study revealed that fenofibrate and simvastatin exerted different effect on the serum free fatty acids of alcoholic fatty liver. Polyunsatrurated fatty acids in the serum play an important role in the pathogenesis and treatment response of alcoholic fatty liver.

OBJECTIVE:
To investigate the clinical application and efficacy of 125Ⅰ radioactive seeds implantation in the treatment of recurrent salivary gland carcinoma after external radiotherapy.
METHODS:
From July 2004 to July 2016, 43 cases of recurrent salivary gland carcinoma of the neck after external radiotherapy or surgery combined with external radiotherapy were treated. According to the conventional segmentation radiotherapy for head and neck cancer (once a day, 1.8-2.0 Gy each time, 5 days per week), the cumulative radiation dose of the patients in this group was calculated. In the study, 26 patients received 50-60 Gy, 7 patients received less than 50 Gy, 4 patients received 60-70 Gy, and 6 patients received more than 80 Gy (range: 80-120 Gy). The interval between the last external irradiation and local recurrence was 4-204 months, and the median interval was 48 months. Among them, 25 cases were treated with 125Ⅰ radioactive seeds implantation only and 18 cases were treated with 125Ⅰ radioactive seeds implantation after operation. The prescription dose was 100-140 Gy. The control rate, survival rate and disease-free survival rate were recorded to evaluate the side effects.
RESULTS:
The median follow-up time was 27 months (ranging from 2.5 to 149.0 months). Among them, the median follow-up time of adenoid cystic carcinoma patients was 31 months (range: 2.5-112.0 months), and the median follow-up time of mucoepidermoid carcinoma patients was 18 months (range: 5-149 months). The local control rates for 1, 3 and 5 years were 66.5%, 48.8% and 42.7%, respectively. The 1-, 3- and 5- year survival rates were 88.0%, 56.7% and 45.8%, respectively. The disease-free survival rates of 1, 3 and 5 years were 58.3%, 45.4% and 38.1%, respectively. There was no statistically significant difference in local control rate, survival rate, and disease-free survival between the radioactive seeds implantation group and the radioactive seeds implantation group after surgical resection. There were 2 cases of acute radiation reaction Ⅰ/Ⅱ and 3 cases of reaction Ⅲ or above. In the late stage of radiotherapy, there were 8 cases with Ⅰ/Ⅱ grade reaction and 3 cases with Ⅲ grade or above reaction. The incidence of radiation reactions of Grade Ⅲ and above was 7%.
CONCLUSION
125Ⅰ radioactive seeds implantation provides an alternative method for the treatment of recurrent salivary gland carcinoma after external radiotherapy. The local control rate and survival rate are improved on the premise of low incidence of side effects.

OBJECTIVETo investigate the effect of Bcl-2 overexpression on Fas and TNFR1-mediated apoptosis and its possible mechanism in rat hippocampus following global ischemia/reperfusion (IR).
METHODSNinety healthy male SD rats were randomly divided into sham operated group, IR group and Bcl-2 overexpression group (BT group). Rat model of global IR was established by the 4-V0 method. The expressions of Bcl-2, Fas and TNFR1 and the cell apoptosis in the CA1 and CA3 regions were examined by HE staining, immunohistochemistry and TUNEL method.
RESULTSIn IR group, the neurons in the CA1 region showed an obvious reduction in number with disordered arrangement and interstitial edema 48 h after global IR. Such changes were not obvious in BT group. Immunohistochemistry showed that Fas expression in the CA1 region reached the peak level at 6 h in IR group with a greater expression intensity than that in BT group (P<0.05). TNFR1 was expressed at a higher level in IR group than in BT group (P<0.05), reaching the peak level at 24 h. In the sham group, the expression of Fas and TNFR1 was not detected the in CA1 and CA3 regions. Global IR caused increased cell apoptosis in the CA1 and CA3 regions, starting at 6 h and reached peak at 24 to 48 h. The cell apoptosis was less obvious in BT group (P<0.05).
CONCLUSIONFas and TNFR1 are expressed in the CA1 and CA3 regions after global IR in rats, suggesting the involvement of death receptor in cerebral IR injury. Bcl-2 overexpression decreases the expression of Fas and TNFR1 and cell apoptosis after global IR, thus offering protective effect against cerebral IR injury.

OBJECTIVETo establish a rat model of focal lymphatic encephalopathy by partial ligation of the cerebral superficial artery for observation of the changes of Virchow-Robin spaces (VRS).
METHODSThirty male SD rats were randomized into 3 groups (n=10), including two model groups and a sham-operated group. The rats in the model groups were subjected to partial ligation of the cerebral superficial arteries under EEG monitoring to induce focal lymphatic encephalopathy, and those in the sham-operated group underwent only dissociation of the cerebral superficial artery without ligation. The rats in the two model groups were executed at 24 and 48 h, and those in the sham-operated group at 48 h following the operation, respectively. Frozen sections of the brain tissues were prepared for microscopic morphological observation and quantitative analysis of the VRS using HE staining and an image analysis system, respectively.
RESULTSEEG remained normal during the operations suggesting intact brain function. Partial ligation of the cerebral superficial arteries resulted in obvious dilation of the VRS in the cerebral cortex and subcortical medulla, and the tissues around the dilated VRSs appeared pale and structurally loosened. The two model groups showed significantly enlarged VRS areas as compared to the sham-operated group (P<0.01), but no significant differences were found in the mean VRS areas between the two model groups.
CONCLUSIONPartial dilation of the cerebral superficial artery is effective and convenient to induce focal lymphatic encephalopathy in rats, and this model can be ideal for studying focal cerebral lymph circulation.
